Visualising spatio-temporal distributions of assimilated carbon translocation and release in root systems of leguminous plants.

ABSTRACT: The release of rhizodeposits differs depending on the root position and is closely related to the assimilated carbon (C) supply. Therefore, quantifying the C partitioning over a short period may provide crucial information for clarifying root-soil carbon metabolism. A non-invasive method for visualising the translocation of recently assimilated C into the root system inside the rhizobox was established using ¹¹CO₂ labelling and the positron-emitting tracer imaging system. The spatial distribution of recent ¹¹C-photoassimilates translocated and released in the root system and soil were visualised for white lupin (Lupinus albus) and soybean (Glycine max). The inputs of the recently assimilated C in the entire root that were released into the soil were approxi
